Yeah, the main reason I would pay for this would be to put the project in my portfolio. I have my own portfolio page though; I wouldn’t be interested in hosting it on a third-party site. Even if it was just something I would link to from my site, I would be concerned that potential employers would see it was “just a tutorial” and write me off as not having the experience in question. That said I don’t often get asked for source code during interviews these days, so probably the ability to host the minified code for a demo would be enough.
